Recurrence quantification analysis of heart rate time series acquired before and after meditation

Author(s)Pooja Prabhu

AbstractCardiac time series show the chaotic behavior. Analyzing the cardiac time series to quantize its periodic nature is a crucial task. Quantizing the periodic nature of heart rate time series in all possible dimension helps in identifying the specific pattern before and after meditation. Fundamental property of non-linear or chaotic system is that at a given sufficient amount of time each state of the system may repeat or may be arbitrarily close to a previously observed state. This is called as recurrence property of a system. Using this property of cardiac time series, Recurrence Quantification Analysis (RQA) is applied to analyze the periodic nature. Cardiac time series of four individuals is acquired before and after meditation. The three parameters obtained after RQA applied over time series, describes the periodic and complex nature of heart rate.
